Climate protesters around the world are calling for an end to fossils fuels as the Earth heats up

Tens of thousands of climate activists around the world are set to march, chant and protest Friday to call for an end to the burning of planet-warming fossil fuels as the globe suffers dramatic weather extremes and record-breaking heat. The strike — driven by several mostly youth-led, local and global climate groups and organizations, including Greta Thunberg's Fridays for Future movement — will take place in dozens of countries and in hundreds of cities worldwide and continue through the weekend. A week before the planned protest, the United Nations warned that countries are way off track to curb warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, as agreed in Paris in 2015.
